   Aurora UI v4.2 · 组件库（前缀版）
   ──────────────────────────────────────────────────────────────────────────
   来源：docs/ui/aurora-ui-canonical.html（设计典范样式，唯一权威源）
   生成：由该底稿自动抽取组件段并统一添加 au- 前缀，请勿手工编辑本文件，
         修改请改底稿后重新生成。

   ★ 前缀规则（重要）
     · 组件类名：典范 .btn        → 落地 .au-btn
     · 状态类名：典范 .is-active  → 落地 .au-is-active
     · 修饰类名：典范 .btn-primary→ 落地 .au-btn-primary
     · 动画名：  典范 spin        → 落地 au-spin
     原因：Aurora 有 27 个类名（btn/tag/modal/pagination/tabs/section-head…）
           与本站既有全站样式重名，加前缀可保证未重构页面零影响。

   ★ 配套：颜色/圆角/阴影/动效令牌统一由 css/themes.css 提供（仅深色 / 浅色）。
